摘要

经过三小时有针对性的搜索，发现了大量黄芪（Astragalus endopterus (Barneby) Barneby），该物种在最近的一篇保护生物学论文（Knapp 等人，2021 年）中被列为灭绝物种。继续搜索发现了数千株植物。我们的工作使该物种的已知分布范围扩大了一倍。黄芪似乎主要分布在片状冲刷沉积物上，这些沉积物主要由风吹砂和可能来自钦勒地层的粘土组成。我们没有迹象表明该物种已经衰退或濒临灭绝。

Astragalus endopterus (Fabaceae), a species purported as extinct, found in northern Arizona, U.S.A.

Astragalus endopterus (Barneby) Barneby, listed as an extinct species in a recent Conservation Biology paper (Knapp et al. 2021) was found in abundance after three hours of targeted searching. Continued searches revealed thousands of plants. Our work has doubled the known range of the species. Astragalus endopterus seems to mostly occur on sheetwash deposits composed of particles derived mostly from windblown sands along with a component of clay probably derived from the Chinle Formation. We have no indications that the species may have been in decline or was ever on the verge of extinction.

期刊介绍： The Journal of the Botanical Research Institute of Texas, formerly called Sida, Contributions to Botany, publishes research in classical and modern systematic botany—including studies of anatomy, biogeography, chemotaxonomy, ecology, evolution, floristics, genetics, paleobotany, palynology, and phylogenetic systematics. Geographic coverage is global. Articles are published in either English or Spanish; an abstract is provided in both languages. All contributions are peer reviewed and frequently illustrated with maps, line drawings, and full color photographs.
